VALVE CONSTRUCTION.

To all whom it may concern Be it known that I, ERNEST G. WAGNER, acitizen of the United States, residing at 'Lewiston, in the county ofNez Force and the valve may be readily opened, the means for opening thevalve being independent thereof, whereby it is impossible for an in.-experienced person to jam the valve against its seat, and means alsobeing provided for independently actuating the valve to pulverize oreject any accumulations of foreign or extraneous matter between thevalve and its seat.

The present invention also contemplates the provision of a valveconstruction of the nature indicated, which will be comparativelysimple, substantial, durable, compact and inexpensive, as well assimple, convenient and efiicient in its use.

lVith the foregoing general objects outlined, and with other objects inview, which will be apparent as the nature of the invention is betterunderstood, the present invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

The invention has been illustrated in its preferred embodiment in theaccompanying drawing, wherein the figure is a longitudinal centralsection of the valve construction.

In carrying out the invention, there is provided a cylindrical body orcasing 1,

preferably in the form of a casting and.

which has one end open. The body or casing 1 is provided with a lateralinlet port 2 adjoining its open end, and with an opposite lateraldischarge port 3 adjoining the other end, the body or casing beingprovided with an inner annular rib or collar 4 intermediate the inletand outlet ports and form;-

ing a contracted opening smaller in diameter than the open end of thecasing.

Driven into or secured within the annular rib or collar 4:, is a valveseat 5 of suitable material, the same being preferably provided with aconical or beveled face at that side adjoining the inlet 2.

A cap 6 is threaded or otherwise engaged over the open end of the bodyor casing 1 and a relatively long guide sleeve 7 has one end threadedoutwardly through a central tap provided in the cap 6, the guide sleeve7 projecting axially into the body or casing 1 to a point near the valveseat, and having a counter bore or socket S in its outer end,

forming a stuffing box in which suitable v. packing 9 is disposed. Agland 10 is threaded into the stuffing box 8 to compress the packing.

A smooth stem or spindle 11 is freely sliclable and rotatable throughthe gland l0 and the guide sleeve 7 and is equipped with a valve 12 atits inner end, between the valve seat and cap and cooperating with thevalve seat 5, the face of the valve being preferably conical or beveledabout its margin, to seat against the face ofthe valve seat in an Thevalve stem 11 is slidable through the guide sleeve 7, to permit thevalve to be seated by the pressure of the fluid entering the inlet port2, the valve being of the check valve type.

The outer end of the valve stem 11 is squared or otherwise formed, as at13, for the engagement of a suitable handle or lever 14, in order thatthe valve may be rotated and forced inwardly, to pulverize or eject anyaccumulation between the valve and its seat.

As a means for opening or unseating the valve, a relatively long plug 15is threaded inwardly through the closed end of the body orvcasing l andprojects to a point near the valve seat, and a spindle or screw 16 isthreaded through the plug 15 so that its tip or inner end is adapted tobe projected respects.

the packing being'compressible against the spindle or screw 16 by meansof the cap 19.

The present valve construction may be employed in divers capacities,suchas, for attaching a sprinkling hose to .a fire .hydrant for a blow-offfor steam boilers, and the like. It will be evident that when the inletport 2 is connected withv any fluid supply, the pressure of the fluidwill normally seat the valve 12, that is, when the screw 16 isretracted. To open the valve, it is merely necessary to run the screw 16inwardly, which will force the valve from its seat against the pressureof the fluid, in order that the fluid may flow through theannularvalveseat and out the. discharge port 3. The valve being of thecheckrvalve type, will close automatically when'the screw 16 isretracted, it being noted that the valve cannot be jammed against thevalve seat through the medium of the screw 16, which will render itimpossible to injure the valve or its seat by inexperienced persons.This is of importance, inasmuch as the amming of a valve against its.seat often results in the destruction or mutilation of the valve or itsseat, which is of disadvantage in other A lthough the valve cannot beforced a ainst its seat, through the medium of the screw 16,'the valvemay be forced inwardly and rotated properly through the medium of thevalve stem 11 and its handle 14, in order that any sediment oraccumulation between the valve and its seat, can be pulverized orejected. The valve stem 11 being smooth and unthreaded, will prevent thevalve, however, from being jammed with excessive force against the valveseat, the valve being released, as soon as the pressure is relieved fromthe valve stem.

Copies ef this patent may be obtained for From the foregoing, taken inconnection with the drawing, the other advantages and capabilities ofthe present device will be apparent to those versed in theart, and-need'not'be itemized at length, it being observed than said open end of thecasing, a capenga'ged over the open end of the casing, a valve seatfitted withinsaid rib, a relatively long plug threaded through the otherend of the casing, a relatively long guide sleeve threaded through thecap, a valve disposed between the valve seat and cap and seatableagainst the valve seat, the valve having a smooth stem slidable androtatable freely through the guide sleeve, a valve unseating screwthreaded through the said plug and adapted to'be projected through thesaid valve seat and abut against the valve, and packing means carried bythe outer ends of the said plug and sleeve and embracing the screw andvalve stem, respectively,- said plug and sleeve projecting to pointsnear the valve seat.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy sig nature in the presence of two witnesses.
